CHARLES SPARKS; O F DOWNERS GROVE, ILLINOIS.

Letters Patent No. 64,805, dated Illa 14, :1867.

IMPROVED COMPOUND FOR WELDING STEEL.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, CHARLES SPARKS, of Downers Grove, in the county of Du Page, in the State of Illinois, have invented a new and improved Compound for Welding Steel without hora-x and I do hereby declare that the followingis a. full and exact description thereof:

Two ounces of copperas, one ounce of saltpetre, one half ounce of sol ammonia, six ounces of common salt, two ounces of sol soda, three pounds of clean send, one pound of. wood ashes; the whole to be thoroughly pulverized together. o

The nature of my invention consists in the use of the above-described compound in welding steel. The nature of the different substances andohemicnls acting together upon the steel causes it to unite equally as well as when borax is employed. The great advantage this compound has over hornx is in its cost. It answers the purpose equally as well, and costs but a small proportion of what born-x would to do the same work.

What I claim as my invention, and desire to secure by Letters Patent, is-

The use of the above-described compound for welding steel.

' C. SPARKS.
